This experiment analyzed the influence of subvocal activity in retention of rhythmical auditory patterns. Retention of sixteen percussion sequences was studied. Each sequence (a 4-s “door-knocking” pattern) was followed by one of the following six retention conditions: silence, unattended music (blocking the inner ear, i.e., Gregorian chanting), unattended music (blocking the inner ear, i.e., rock-and-roll), articulatory suppression (blocking the inner voice), tracing circles on the table with index finger (spatial task), and tapping (motor control). After silence, unattended music (chanting), or the spatial task, participants successfully reproduced most patterns. Errors increased with unattended music (rock-and-roll), but significant disruptions only occurred with tapping and articulatory suppression. Whereas the latter case supports the role of an articulatory loop in retention, the production of successive taps or syllables in both interference conditions probably relies on a general rhythm module, which disrupted retention of the patterns.
